Used primarily as a plasticizer in polymer formulations to improve flexibility and durability of plastics. Commonly found in PVC and other vinyl applications where low-temperature performance and resistance to water extraction are required. Also serves as a solvent and carrier in chemical processes due to its low volatility and good solvency properties. Employed in the formulation of lubricants and hydraulic fluids for enhanced thermal stability. Occasionally used in specialty extraction processes and as a component in some cosmetic and personal care products where mild, non-irritating solvents are needed.
